Evidence for independent development of resistance to HIV-1 reverse transcriptase inhibitors in the cerebrospinal fluid

Abstract

Differences in the positions and frequencies of wild-type and drug selected variants in specimens derived from the CSF and blood compartments were detected in a significant number of patients; this argues for the independent development of drug resistance in the CNS in some patients. These findings may have important implications in guiding antiretroviral therapy in HIV-1 infection.
